ADP2360ACPZ-5.0-R7 개요
A buck (step-down) switching regulator is a DC-to-DC converter that uses an internal switch, an inductor, and a rectifier to transfer energy from input to output at a duty cycle that sets the output voltage below the input. Synchronous buck regulators replace the external Schottky rectifier with an internal low-side MOSFET, which improves efficiency at light loads and shrinks the bill of materials. The ADP2360 specifically uses a single-pulse pulse-frequency-modulation (PFM) architecture with adjustable peak-current control, minimizing both input and output ripple while allowing the designer to optimize efficiency for the application's operating conditions and minimize the compatible inductor size.
Key features of the ADP2360ACPZ-5.0-R7 include a fixed 5.0V output (no external feedback resistors required), wide 4.5V to 60V input operating range, up to 50mA continuous output current, adjustable peak current limit via an external resistor, integrated P-channel high-side switch and N-channel low-side switch, internal soft-start, and a power-good (PG) output that indicates when VOUT is within regulation. The 8-pin LFCSP exposed-pad package provides a low thermal-resistance path and a compact footprint for industrial sensor modules, factory-automation nodes, and battery-powered remote transmitters.
The PFM control topology is well suited to low-duty-cycle, light-load applications because it skips switching cycles when the output is in regulation, holding quiescent current to a minimum. A power-good flag simplifies interface to downstream microcontrollers and enables sequenced multi-rail power-up. The device is specified for operation from -40C to +125C junction temperature and is qualified for automotive and harsh-environment use cases.
Typical applications include 4-20mA current-loop powered sensor transmitters, industrial process-control loops, automotive body and sensor electronics, battery-powered remote telemetry, and isolated low-power bias supplies. The high input-voltage tolerance allows direct connection to 24V industrial buses or 12V/24V automotive rails without pre-regulation.
When designing with the ADP2360ACPZ-5.0-R7, choose the input capacitor, output capacitor, and inductor per the datasheet's selection tables to maintain stable DCM operation. A small ceramic input capacitor is typically sufficient because the PFM architecture draws input current only during the high-side switch on-time; the exposed pad must be soldered to a thermal land on the PCB for proper heat dissipation.

일반적인 애플리케이션
ADP2360ACPZ-5.0-R7 적합 용도: 6 애플리케이션s: 4-20 mA Current-Loop Powered Sensor Transmitter, Industrial 24V Rail Bias Supply, Automotive 12V/24V Body Electronics Bias, Battery-Powered Remote Telemetry, Isolated Low-Power Bias Supply, HVAC and Building-Automation Sensor Nodes.
4-20 mA Current-Loop Powered Sensor Transmitter
The ADP2360ACPZ-5.0-R7 is purpose-built for 4-20 mA current-loop-powered field instruments where the loop itself supplies the input current to the transmitter. Its 4.5V to 60V input tolerance allows direct connection to the loop's compliance voltage (typically 24V nominal), and the fixed 5.0V output at 50mA continuously powers the sensor, ADC, and microcontroller. The PFM DCM topology keeps quiescent draw low, leaving more of the 4 mA loop budget for actual sensing rather than housekeeping. The exposed-pad LFCSP package fits inside the small head of a typical field transmitter enclosure.
추천
Industrial 24V Rail Bias Supply
In factory automation and process-control systems, the ADP2360ACPZ-5.0-R7 regulates a 24V industrial bus directly down to 5.0V without requiring any upstream pre-regulator. The 60V absolute-maximum input withstands the inductive transients common on long industrial cables, and the 50mA output current comfortably powers sensor interfaces, isolated transceivers, and low-power microcontrollers. The synchronous-rectifier topology achieves high efficiency even at the large 24V-to-5V step-down ratio, eliminating the heatsink that an equivalent LDO would require.
추천
Automotive 12V/24V Body Electronics Bias
The ADP2360ACPZ-5.0-R7's AEC-Q100 qualification, -40C to +125C operating range, and 60V load-dump tolerance make it ideal for automotive body-control modules, sensor bias, and accessory-power applications. It generates a clean 5.0V rail from the 12V or 24V vehicle bus to power dashboard sensors, interior lighting controllers, and remote keyless-entry receivers. The internal soft-start prevents inrush current on cold-crank events, and the power-good output flags regulation status to the host microcontroller for diagnostic logging.
추천
Battery-Powered Remote Telemetry
In remote telemetry units (RTUs) powered by primary lithium batteries or energy-harvesting sources, the ADP2360ACPZ-5.0-R7 provides efficient step-down conversion from a high-voltage battery stack to a 5.0V logic rail. The PFM DCM control skips cycles at light load, extending battery life between replacement intervals, and the 50mA output is sufficient to power a low-duty-cycle wireless sensor node. The wide 4.5V to 60V input range allows the same regulator design to scale across multiple battery chemistries and cell-stack configurations.
추천
Isolated Low-Power Bias Supply
In isolated data-acquisition and interface modules, the ADP2360ACPZ-5.0-R7 generates the primary-side 5.0V bias rail that powers the isolated transceiver and the isolated side of the digital isolator. The 60V input tolerance allows direct operation from industrial 24V or higher-voltage DC distribution. The small LFCSP footprint enables the bias supply to fit alongside the isolation barrier on the same PCB side, simplifying layout and minimizing creepage-distance violations on the high-voltage side.
추천
HVAC and Building-Automation Sensor Nodes
Building-automation systems frequently operate from 24VAC rectified supplies or 24VDC distribution rails, both of which the ADP2360ACPZ-5.0-R7 accepts directly. The 5.0V output powers temperature, humidity, CO2, and occupancy sensors, along with the wireless transceiver that reports back to the building-management system. The power-good output can wake a sleeping radio only after the supply has stabilized, and the wide temperature range supports rooftop and unconditioned-space installations.

설계 노트
The exposed pad (EP) of the 8-pin LFCSP must be soldered to a PCB ground land - failure to do so will cause the part to overheat and shut down under normal load. The land should be a continuous copper pour connected to the system ground plane with multiple thermal vias underneath. The input capacitor, output capacitor, and inductor should be placed as close as possible to the IC pins to minimize parasitic inductance in the switching loop, which reduces EMI and improves efficiency. The RT/SS resistor should be placed close to pin 8 to avoid noise pickup.
The switching node (SW, pin 1) carries high dv/dt signals and should be kept away from sensitive analog traces such as the feedback and power-good paths. A small ground-shielded keepout zone around the inductor and SW node minimizes coupling into adjacent signal traces. The input capacitor return path should be a wide, short trace directly to the GND pin to handle the discontinuous input current that flows during the high-side switch on-time. Avoid routing any signal trace directly beneath the inductor to prevent magnetic coupling.
Estimated junction temperature for worst-case steady-state conditions. At VIN = 24 V, V_OUT = 5.0 V, I_OUT = 50 mA, the regulator's typical efficiency is roughly 85%, so internal power dissipation is roughly (24 * 0.05) * (1 - 0.85) / 0.85 = approximately 0.21 W. With the 8-pin LFCSP exposed-pad package mounted on a 1-square-inch copper land on a standard 4-layer FR4 PCB, theta_JA is roughly 50 C/W, yielding a junction temperature rise of about 10 C above ambient - well within the -40 C to +125 C rating. At 60 V input, dissipation rises to roughly 0.5 W and junction temperature rise to 25 C, still safe.
Do not exceed the absolute maximum input voltage of 60 V - even brief transients above this rating can permanently damage the internal MOSFETs. Do not operate the part without the output capacitor in place - instability and excessive output ripple will result. The RT/SS resistor value sets both the peak current limit and the soft-start time; consult the datasheet selection table to choose a value appropriate for the application's inductor and required startup time. When using the adjustable-output variant (ADP2360ACPZ-R7), do not leave the FB pin floating - it must be connected to the resistor divider between VOUT and GND.
The PFM DCM control topology minimizes quiescent current at light loads by skipping switching cycles when the output is in regulation. This makes the ADP2360ACPZ-5.0-R7 well-suited to battery-powered applications where standby current dominates total energy consumption. However, the output voltage ripple at light load is higher than with a fixed-frequency PWM regulator because the pulses are spread further apart in time - a larger output capacitor can be selected if lower ripple is required. The power-good output can be used to disable downstream circuits when the input voltage falls below the UVLO threshold, preventing brownout-induced misoperation of the host microcontroller.
